Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, and in particular to a safety valve that is easy to install. Background Technology

[0002] A safety valve is an automatic pressure relief device that opens under static pressure. It is one of the most important safety accessories for pressure vessels. Existing safety valves, for the sake of their sealing, typically use threaded connections. A problem with this installation method is that the threads corrode during use. All valves require periodic maintenance, which necessitates disassembling the safety valve from the equipment. With threaded safety valves, repeated disassembly and reassembly can lead to rust and wear, causing the connection to jam or the interface to become severely worn, making it difficult to seal. Therefore, the entire safety valve may need to be replaced, significantly increasing maintenance costs.

[0003] The existing technology (CN215293750U) discloses a safety valve structure that is easy to install, including a protective shell, a spring plate slidably connected to the inner wall of the protective shell, a connecting block fixedly installed at the lower end of the spring plate, a fixing ring fixed at the lower end of the connecting block, a sealing ring fixedly installed at the lower end of the fixing ring, a connecting pipe fixedly installed at the lower end of the sealing ring, a fixing groove opened on the surface of the protective shell, a fixing rod movably connected to the inner wall of the fixing groove, grooves opened at both ends of the fixing rod, a locking block fixedly engaged at the inner wall of the groove, a connecting plate fixedly installed at the other end of the locking block, and a connecting plate slidably connected to the inner wall of the protective shell. This utility model, through the internal structure of the protective shell, allows the grooves at both ends of the fixing rod to engage with the locking blocks, and through the internal spring, the sealing ring blocks the gap at the connection between the installation pipe and the connecting pipe, thereby increasing the sealing effect of the device and improving the practicality of the device.

[0004] However, the above solution does not restrict the position of the mounting block, which leads to an unstable connection and makes it easy to loosen. Utility Model Content

[0005] The purpose of this utility model is to provide a safety valve that is easy to install, in order to solve the problem that existing safety valves that are easy to install involve sliding the mounting block into the groove for installation without any position restrictions, resulting in an unstable connection and easy loosening.

[0006] To achieve the above objectives, this utility model provides a safety valve that is easy to install, including a connecting pipe and an installation assembly. The installation assembly includes a connector, an installation pipe, a protective shell, a connecting shaft, a first limiting member, a drive shaft, an installation shaft, a second limiting member, and a limiting component. The connecting pipe has a first limiting groove located on one side of the connecting pipe. The connector is fixedly connected to the connecting pipe and located on one side of the connecting pipe. The installation pipe is fixedly connected to the connector and located on one side of the connector. The installation pipe has a second limiting groove located on one side of the connecting pipe. On one side of the mounting tube, the protective housing is located on one side of the mounting tube, the connecting shaft is fixedly connected to the protective housing and located on one side of the protective housing, the first limiting member is fixedly connected to the connecting shaft and located on one side of the connecting shaft, the drive shaft is fixedly connected to the connecting shaft and located on one side of the connecting shaft, the mounting shaft is fixedly connected to the drive shaft and located on one side of the drive shaft, the second limiting member is fixedly connected to the mounting shaft and located on one side of the mounting shaft, and the two limiting members are respectively disposed on one side of the protective housing.

[0007] The limiting component includes a limiting frame, a mounting ring, and a telescopic part. The limiting frame is rotatably connected to the connecting pipe and is located on one side of the connecting pipe. The mounting ring is fixedly connected to the protective shell and is located on one side of the protective shell. The telescopic part is located on one side of the mounting ring.

[0008] The telescopic part includes a spring, a push plate, and a limiting post. The spring is fixedly connected to the mounting ring and is located on one side of the mounting ring. The push plate is fixedly connected to the spring and is located on one side of the spring. The limiting post is fixedly connected to the push plate and is located on one side of the push plate.

[0009] The installation assembly also includes a discharge pipe, which is fixedly connected to the protective housing and located on one side of the protective housing.

[0010] The mounting assembly also includes a sealing ring, which is disposed on one side of the connecting pipe.

[0011] This utility model discloses a safety valve that is easy to install. The first limiting member on the side of the connecting shaft is aligned with the second limiting groove on the mounting tube and slid. When the protective shell slides to the position of the connecting member, it is rotated again to align with the misaligned first limiting groove in the connecting tube, and the first limiting member is slid into the first limiting groove. Then, the second limiting member of the protective shell is rotated to align with the second limiting groove, and the first and second limiting members are slid into the first and second limiting grooves respectively, so that the connecting shaft is inside the connecting tube, the drive shaft is inside the connecting member, and the mounting shaft is inside the mounting tube, completing the installation. The misalignment method provides restriction, and the limiting members further restrict the connection to ensure a secure fit. This solution solves the problem in existing easy-to-install safety valves where the mounting block is slid into a groove for installation without a restrictive position, resulting in an unstable connection and a tendency to loosen.

[0021] This utility model provides a safety valve that is easy to install, including a connecting pipe 101 and an installation assembly 102. The installation assembly 102 includes a connector 103, an installation pipe 104, a protective shell 105, a connecting shaft 106, a first limiting member 107, a drive shaft 108, an installation shaft 109, a second limiting member 110, two limiting components 111, a discharge pipe 120, and a sealing ring 121. The limiting component 111 includes a limiting frame 114, an installation ring 115, and a telescopic part 116. The telescopic part 116 includes a spring 117, a push plate 118, and a limiting post 119. The aforementioned solution solves the problem in existing safety valves that are easy to install, where the installation block is slid into the groove for installation without a restricted position, resulting in an unstable connection and easy loosening.

[0022] In this specific embodiment, the connecting pipe 101 has a first limiting groove 112, which is located on one side of the connecting pipe 101. The connecting member 103 is fixedly connected to the connecting pipe 101 and is located on one side of the connecting pipe 101. The mounting pipe 104 is fixedly connected to the connecting member 103 and is located on one side of the connecting member 103. The mounting pipe 104 has a second limiting groove 113, which is located on one side of the mounting pipe 104. The protective shell 105 is located on one side of the mounting pipe 104. The connecting shaft... 106 is fixedly connected to the protective housing 105 and located on one side of the protective housing 105; the first limiting member 107 is fixedly connected to the connecting shaft 106 and located on one side of the connecting shaft 106; the drive shaft 108 is fixedly connected to the connecting shaft 106 and located on one side of the connecting shaft 106; the mounting shaft 109 is fixedly connected to the drive shaft 108 and located on one side of the drive shaft 108; the second limiting member 110 is fixedly connected to the mounting shaft 109 and located on one side of the mounting shaft 109; the two limiting members 111 are... The first limiting member 107 on the side of the connecting shaft 106 is aligned with the second limiting groove 113 on the mounting tube 104 and slid. When the protective shell 105 slides to the position of the connecting member 103, it is rotated again to align with the first limiting groove 112 in the misaligned connecting tube 101, and the first limiting member 107 is slid into the first limiting groove 112. When the protective shell 105 is rotated, the second limiting member 110 will align with the second limiting groove, and the first limiting member 107 and the second limiting member 110 will be aligned. 10 is slid into the first limiting groove 112 and the second limiting groove 113 respectively, so that the connecting shaft 106 is in the connecting tube 101, the driving shaft 108 is in the connecting member 103, and the mounting shaft 109 is in the mounting tube 104, thus completing the installation. The connection is restricted by the misalignment method, and then restricted by the limiting member 111 to ensure the connection is firm. The above solution solves the problem that in the existing safety valves that are easy to install, the mounting block is slid into the slide groove for installation, but there is no position to restrict it, which leads to the connection being unstable and prone to loosening.

[0023] The limiting frame 114 is rotatably connected to the connecting pipe 101 and located on one side of the connecting pipe 101. The mounting ring 115 is fixedly connected to the protective shell 105 and located on one side of the protective shell 105. The telescopic part 116 is disposed on one side of the mounting ring 115. The limiting frame 114 is located on both sides of the connecting pipe 101. After the protective shell 105 and the connecting pipe 101 are connected, the limiting frames 114 on both sides are rotated, and the contraction part on the mounting ring 115 is pressed to contract and lock the limiting frame 114 on the mounting ring 115. Then the telescopic part 116 is released to restrict it.

[0024] Secondly, the spring 117 is fixedly connected to the mounting ring 115 and located on one side of the mounting ring 115. The push plate 118 is fixedly connected to the spring 117 and located on one side of the spring 117. The limiting post 119 is fixedly connected to the push plate 118 and located on one side of the push plate 118. When restricting, pressing the limiting post 119 pushes the spring 117 to elastically deform and contract. After the limiting frame 114 is locked, the limiting post 119 is released. The elastic deformation of the spring 117 pops the limiting post 119 out of the mounting ring 115 to restrict.

[0025] Meanwhile, the discharge pipe 120 is fixedly connected to the protective shell 105 and located on one side of the protective shell 105. The discharge pipe 120 is fixed to the right side of the protective shell 105 to facilitate material discharge from the device.

[0026] In addition, the sealing ring 121 is disposed on one side of the connecting pipe 101. The sealing ring 121 is made of fluororubber and has a certain elasticity and shrinkage. After the connection is completed, the sealing ring 121 is put on the connection between the connecting pipe 101 and the protective shell 105 to cover it.

[0027] When using this utility model, the first limiting member 107 on the side of the connecting shaft 106 is aligned with the second limiting groove 113 on the mounting tube 104 and slid. When the protective shell 105 slides to the position of the connecting member 103, it is rotated again to align with the first limiting groove 112 in the misaligned connecting tube 101, and the first limiting member 107 is slid into the first limiting groove 112. Rotating the protective shell 105 will align the second limiting member 110 with the second limiting groove, and the first limiting member 107 and the second limiting member 110 are slid into the first limiting groove 112 and the second limiting groove 113 respectively, so that the connecting shaft 106 is inside the connecting tube 101, and the drive shaft... The safety valve is installed by placing the mounting shaft 109 inside the mounting tube 104 and the mounting pin 108 inside the connector 103. The installation is restricted by a misalignment. Then, the limiting post 119 is pressed down to push the spring 117 to elastically deform and contract. After the limiting frame 114 is secured, the limiting post 119 is released. The elastic deformation of the spring 117 causes the limiting post 119 to pop out of the mounting ring 115 for restriction. The sealing ring 121 is then fitted onto the connection between the connector 101 and the protective housing 105. This solution addresses the problem in existing safety valves where the mounting block slides into the groove for installation without a restricted position, leading to unstable connections and a tendency to loosen.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
